Same job ads appeared for the original Bioshock, so this means nothing. On the other hand, the original was only a moderate commercial success on 360/PC so it is unlikely that MS would pay for permanent exclusivity on the basis of prestige alone. You will probably see a double pack with both games on the PS3 6-12 months after the release of part 2 on 360/PC.
Either way, it's not going to sell systems for anybody.
